Will `ids` become a property/attribute of `W` object in future? I've not seen many snippets where it's used NVM looks like its solved already :)

@darribas @slumnitz

@ljwolf if this issue is still open...Could I get assigned to this?

@ljwolf Can you also tell me the difference between these 2 functions... what i understand is they both return different types of output and offer different contiguity weight matrix to...

@ljwolf I was having a doubt...here you want me to merge both the functions while also keeping the necessary properties described by these statements... > make the sparse constructor lat2SW...

Thnx! I understand it now! I'll try to solve it today...

@ljwolf is the order of arrangement of neighbors important? after converting sparse weights to dense weights using lat2SW....the neighbors for each point in lattice are returning in sorted order... earlier...

@ljwolf whenever u r free can you review if my implementation is correct in this [pr](https://github.com/pysal/libpysal/pull/256)

Probably a bug, lemme check!

> whoops, should've left this for you MgeeeeK, sorry :/ just saw in morning email & recalled the standardization options... https://github.com/pysal/libpysal/blob/0f03a313896de6af096ff92105e54da86bb78368/libpysal/weights/raster.py#L301 no problem! I think you are correct, [sparse weights](https://github.com/pysal/libpysal/blob/0f03a313896de6af096ff92105e54da86bb78368/libpysal/weights/weights.py#L1314)...
